The active-low, open-drain output can be pulled up to any voltage independent of the monitored rail, making it suitable for mixed-voltage systems. With a typical reset timeout of 50 µs, the part recovers quickly once the supply returns above threshold. The SOT-23-5 package fits compact PCB layouts in industrial controls, automotive ECUs, and portable equipment where reliable power-on reset is required. ## Threshold adjustability — why it matters for your rail The threshold is adjustable/selectable via external resistors, so the same part can be configured for any supply level within the device's operating range. The open-drain output allows the reset signal to be pulled up to the logic voltage of the downstream microcontroller or FPGA, even if that differs from the monitored supply. ## Temperature grade and deployment environment Rated for -40°C to 125°C ambient, this part covers the full industrial temperature span and extends into automotive under-hood and engine-bay environments. The SOT-23-5 package is a standard footprint shared by many reset ICs, simplifying board layout and second-sourcing. ## Lifecycle and sourcing posture The MAX6458UKD0C+T carries an Active lifecycle status with ROHS3 compliance. There is no last-time-buy or obsolescence risk for this order code.","metaTitle":"MAX6458UKD0C+T Simple Reset/Power-On Reset, SOT-23-5, Active","metaDescription":"MAX6458UKD0C+T is an active Simple Reset/Power-On Reset IC from Maxim Integrated.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Simple Reset/Power-On Reset","Reset":"Active Low","Output":"Open Drain or Open Collector","Package":"Bulk","Mounting Type":"Surface Mount","Reset Timeout":"50µs Typical","Package / Case":"SC-74A, SOT-753","lifecycle_stage":"eol_hot","Voltage - Threshold":"Adjustable/Selectable","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"SOT-23-5","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.55","stockQuantity":0,"priceTiers":[{"qty":120,"price":"$2.55000","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX6457-MAX6460.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is MAX6458UKD0C+T obsolete or still active?","answer":"The MAX6458UKD0C+T is listed as Active with ROHS3 compliance.
